selling hypnosis

Your post, Roger, was one that I needed more. Actually, I want to learn about this topic as much as possible. I even bought an e-book on this. But still I couldn't get the info I seek for. I'm amazed to see how these sales assistants in the markets make me buy something which is not in my shopping list, without even saying a word and as I am just leaving their stand. They make me turn back and take their product from the shelf. NO WORDS. If only I had that power!! How easy life would be!! Who can enlighten me about their silent process?
